Quick Answer

The pick worth your money is a hand-wound 1:1 fake Saxonia Big Date with a working two-disc outsize date, a movement you can inspect through a sapphire caseback, and a 38.5mm case that copies the original Saxonia Outsize Date geometry. Judge every candidate on four points: how the big date changes, what the movement looks like, how close the case and dial sit to the genuine watch, and whether the seller will service the piece after the sale. Boxes, papers and holograms matter far less than those four.

How the Outsize Date Should Behave

Lange's outsize date is two discs, not one printed wheel. A units disc and a tens disc sit side by side in a single aperture at 12 o'clock, and the mechanism is patented. On the genuine watch the tens window stays blank from the 1st to the 9th, then shows 1, 2 or 3, with both discs sharing one baseline. Cheap fakes fail here in three ways: a zero appears in front of single-digit dates, the two discs sit at different heights, or the date creeps across several hours instead of snapping at midnight. Ask for a video of the date change before you pay.

Tier A: Hand-Wound 1:1 Builds

These copy the hand-wound layout of the calibre L086.1, including the three-quarter plate, blued screws, engraved balance cock and a 72-hour-class power reserve. The caseback is sapphire, so finishing is on display every time you turn the watch over.

  • Pros: correct hand-wound architecture, outsize date that jumps, dial furniture set in the right positions, weight and thickness close to the original.
  • Cons: the highest outlay of the three tiers, the hardest to source in stock, and service means a watchmaker who knows Lange-style movements.

Best for collectors who take the watch off and hand it around, and for anyone who wants the caseback to survive a close look.

Tier B: Automatic Builds with a Simulated Outsize Date

This is the middle of the market. The case and dial are often convincing, but the movement is an automatic with a decorated rotor, and the date is a single disc behind a wide aperture or two discs driven by a simpler cam.

  • Pros: lower price, easier to find, automatic winding suits daily wear, dial printing and hands can still be sharp.
  • Cons: date action gives the watch away, rotor and bridges look nothing like a Lange movement, thickness often runs over the original.

Best for buyers who wear the watch on the wrist all day and rarely show the back.

Tier C: Quartz and Printed-Date Fakes

Quartz Saxonia copies usually print or stamp the date rather than change it, and the seconds hand ticks. They are the least convincing and the least repairable.

  • Pros: lowest cost, light, accurate timekeeping, fine as a knock-around watch.
  • Cons: ticking seconds hand, dead or fake date, no meaningful movement finishing, plating that wears through.

Best for a costume or a test run before you commit to a higher tier.

Details That Separate a Strong Fake from a Weak One

  • Date aperture: two discs, one baseline, blank tens window for days 1 to 9.
  • Case: 38.5mm class diameter, straight lugs, polished bezel, correct lug width for the strap you plan to fit.
  • Dial: applied markers, printed railway track, hands with the right length and taper.
  • Movement: hand-wound, visible finishing, no rotor on a Saxonia replica, no quartz tick.
  • Crown: pulls to one date-setting position, feels solid, threads or seats without wobble.

Choosing Your Tier

If the watch will be handled, worn to dinners and passed around, go for Tier A. If it is a daily wearer that stays on your wrist, Tier B gives you most of the look for less. If you want the silhouette for a single occasion, Tier C covers that. In every case, confirm the date action on video and ask what happens if the mechanism stops working within the first months.
